Lists

list<T> stores elements of one type. Indices start at 0.

mcfpp

func main() {
    var rewards: list<int> = [10, 20]
    rewards.add(30)
    rewards.removeAt(0)

    print(rewards[0])
    print(rewards.size())

    for (reward: rewards) {
        print(reward)
    }
}

After removal, the list is [20, 30]. rewards[0] is 20 and size() is 2.

Common methods

Method	Purpose
`add(value)`	Append an element
`prepend(value)`	Insert at the start
`addAll(values)`	Append several elements
`insert(index, value)`	Insert at an index
`removeAt(index)`	Remove an indexed element
`remove(value)`	Remove a matching value
`contains(value)`	Test for a value
`indexOf(value)`	Find an index
